Abstract:
Four key issues in wavelet zero-tree based image coding are investigates and presented they are 1 Fast wavelet transform that save 112 and 34 processing for one dimensional signal and two dimensional signals respectively. 2 The selection of the best wavelet filters that yields best performance PSNR vs. Bit rate for most common seen images. 3 Recommendation of number of wavelet scales or frequencies for image coding by experiments and analysis.
